probably I did. I checked out Linux tip again and applied the patch on
top of it and rebuild. Funny that it applied twice. ;-)

Now it works:

Perfect.

I was also wondering why it was telling me that this is v3.8 so I
probably used the wrong branch.

Thanks again. Btw. Yesterday I already bisected the problem and always
booted the same kernel. So I had to repeat the bisecting this morning.
40 Kernels later I had identified the commit. And the Mac Mini takes an
awful long time to boot. And the core duo is also not the fastet CPU
around.

Cheers,
